Pronto - Find Predicates in Ontologies Fast
If you work with linked data or the semantic web, you understand how dull digging through ontologies to find concepts and predicates can be. At Wallscope we understand this too – so we created Pronto, a free tool that makes this work easier and more efficient.
(If you are new to the semantic web and link data, I suggest you have a look at the type of challenges it aims to solve first.)
The Problem. The reuse of ontologies is a critical aspect of their existence as a means of knowledge representation. Although this is a simple concept, it can prove inconvenient in the long run. The many existing ontologies make searching for concepts and predicates tedious, labour-intensive and time-consuming. One has to iteratively and manually inspect a number of ontologies until a suitable ontological component is found.
At Wallscope this issue impacts us since our work includes building data exploration systems that connect independent and diverse data sources. So we started thinking.
It would be much easier to search through all ontologies — or at least the main ones — at the same time.
As a result, we decided to invest in the creation of Pronto with the aim to overcome this challenge.
The Solution. Pronto allows developers to search for concepts and predicates among a number of ontologies, originally selected from the prefix.cc user-curated “popular” list, along with some others we use. These include:

Searching for a concept or a predicate retrieves results from the above ontologies, ordered by relevance.

Thanks for reading. We would be interested to hear your feedback or suggestions for others ontologies to include. If you find Pronto useful give the article some claps (up to 50 if you hold the button 😄) so that more people can benefit from this tool!
